Ossifying fibroma is a benign, slow growing, and expansile lesion of the jaws. It is classified as one of the benign fibro-osseous lesions of the jaws. The juvenile ossifying fibroma (JOF) is commonly found in children and young adults. The juvenile variety of ossifying fibroma is more aggressive and requires a more extensive therapy because it might recur after curettage. It usually occurs in the mandibular premolar-molar area. The slow growth of the tumor may produce expansion and thinning of the buccal and lingual cortical plates. The treatment of the JOF is conservative surgical contouring either using curettage or enucleation. The lesion can be separated easily from the surrounding normal bone. Large ossifying fibroma requires surgical resection to reestablish normal facial symmetry. A long-term follow up is required for the lesion.
